This faucet is beautiful, and I expect it to last a lifetime. However, it is difficult to install. You'll need a 1-1/4" wrench to tighten the nuts under the valve body, which go below the countertop. Since it's so difficult to reach this area, you'll likely need a basin wrench to tighten them. Moen should consider making the valve bodies easier to install--that would greatly shorten the install time.
